The European Union has taken a leading role in promoting transparency and accountability in corporate sustainability. As part of its broader climate and economic strategy, the EU has introduced a comprehensive regulatory framework to improve how companies disclose environmental, social, and governance (ESG) information.
The EU Taxonomy and the Corporate Sustainability Reporting Directive (CSRD) provide complementary frameworks that guide companies in reporting their environmental performance and sustainability impacts in a consistent, transparent, and comparable way. These regulations are a cornerstone of the EU’s broader sustainability agenda under the European Green Deal.
These frameworks are designed to redirect capital toward environmentally sustainable activities and to improve the quality of non-financial disclosures. As regulatory expectations increase, organisations must move beyond voluntary sustainability reporting toward structured, verifiable, and standardised disclosures.
How the frameworks work together
The EU Taxonomy provides the technical screening criteria for determining whether an economic activity can be considered environmentally sustainable. It focuses on six key environmental objectives, including climate change mitigation, climate change adaptation, and the protection of biodiversity and ecosystems. To qualify as Taxonomy-aligned, an activity must substantially contribute to one of these objectives, do no significant harm to the others, and meet minimum social safeguards.
The CSRD, on the other hand, establishes how and what companies must report. It significantly expands the scope and depth of sustainability reporting requirements, replacing and strengthening the previous Non-Financial Reporting Directive (NFRD).
CSRD entered into force in January 2023, and significantly expands both the scope and depth of sustainability reporting requirements. In essence, the CSRD transforms sustainability reporting from a largely flexible exercise into a structured, regulated system comparable to financial reporting.
The CSRD represent a major upgrade from NFRD by:
- Expanding the scope to nearly 50,000 companies
- Introducing mandatory reporting standards
- Requiring assurance of reported data
- Strengthening enforcement and accountability
Under CSRD, companies must disclose detailed information on environmental, social, and governance (ESG) topics, following the European Sustainability Reporting Standards (ESRS).
Both the EU Taxonomy and the CSRD create a structured and interconnected approach:
- The EU Taxonomy defines what qualifies as sustainable
- CSRD defines how sustainability information is disclosed
In practice, companies identify their Taxonomy-eligible and Taxonomy-aligned activities, assess their environmental performance, and then disclose this information within their CSRD reports. This alignment ensures that sustainability disclosures are not only consistent but also meaningful for investors, regulators, and other stakeholders.
Key reporting requirements under CSRD
Under CSRD, organisations are required to provide more granular and forward-looking disclosures than ever before. Key elements include:
- Double materiality assessment, considering both financial risks and environmental/social impacts
- Disclosure of climate-related risks and opportunities
- Reporting on greenhouse gas emissions (Scope 1, 2, and increasingly Scope 3)
- Information on transition plans aligned with climate goals
- Integration of sustainability into governance, strategy, and risk management
Additionally, reported information must be digitally tagged and subject to independent assurance, increasing reliability and comparability across companies.
Implementation challenges for organisations
Implementing the EU Taxonomy and CSRD can be complex, particularly for organisations with diverse operations or global supply chains. Companies must:
- Map business activities against Taxonomy criteria
- Interpret technical screening requirements
- Collect high-quality, auditable ESG data
- Align internal systems, controls, and governance structures
Many organisations also face challenges in assessing “do no significant harm” criteria and ensuring compliance with minimum social safeguards. As a result, cross-functional collaboration between sustainability, finance, legal, and operations teams is essential.
Global relevance and evolving impact
Although primarily focused on the EU, the impact of the EU Taxonomy and CSRD extends far beyond its borders. These frameworks are shaping global sustainability reporting practices and influencing other regulatory regimes, including those in the UK, Asia, and the Middle East.
Multinational organisations often adopt EU-aligned reporting standards across their global operations to ensure consistency and meet investor expectations. Financial institutions, in particular, are increasingly using Taxonomy-aligned data to inform investment decisions and assess sustainability risks.
